Display and device technology is constantly evolving. So are we. Behind the simplicity of our products lies the powerful combination of optics and sheer ingenuity you expect from 3M. The microlouvre technology of our premium privacy filters helps protect the confidential and sensitive information displayed on your screen. The matte finish helps reduce glare and fingerprints, giving your laptop a crisp and clear image display while keeping visual hackers looking from the side in the dark. 3M™ Standard Laptop Privacy Filters offer premium privacy protection by "blacking out" side views beyond a 60-degree viewing angle, while providing an excellent high-resolution viewing experience when viewed from the front. Reversible: one glossy side and one matte side to reduce glare - this reduces reflections and hides fingerprints, so you enjoy flawless image clarity.
